Product Information
DescriptionThe Desander hydrocyclone, designed to remove sand-size particles, and the Desilter hydrocyclone, designed to remove silt-sized particles, should be the second stage of a solids removal program for unweighted muds. To achieve maximum benefit from these units, install them as recommended.
These specially designed hydrocyclones are made from a durable polymeric material developed exclusively for NOV Brandt. The involute feed entry design (rather than the conventional tangential entry commonly used in the industry) increases the hydrocyclones' handling capacity up to 25%. Other advantages are more efficient drilled solids separation, less drilling fluid is discarded, and reduced wear at the feed inlet.
The Hydrocyclone Systems consist of an assembled hydrocyclone, a separate overflow and underflow manifold, and a discard trough for the underflow. The hydrocyclones are available as a 12” Desander, 10” Desander, and 4” Desilter. The size designation is the inside diameter of the hydrocyclone. In general, the cut point of the hydrocyclone decreases as the inside diameter decreases.
The number of hydrocyclones should be selected to process approximately 110 - 125% of the maximum circulating rates expected in top hole drilling. This will ensure treatment of 100% of the circulating volume containing formation contaminants.
Equal importance should be given to selecting a suitable centrifugal pump and prime mover (engine or electric motor) that will deliver the required flow rate and feet of head/pressure to the feed manifold.
Properly installed, maintained and utilized, the hydrocyclone will reduce rig pump maintenance, improve penetration rates and improve hole conditions.
A properly installed and correctly operated hydrocyclone will be a cost effective mechanical device for the reduction of undesirable contaminants in following mediums.

Installation
The hydrocyclones should be mounted so that the feed manifold is ABOVE THE MAXIMUM mud level in the tanks. This prevents the mud from the tanks being siphoned through the cones and into the waste pit when the feed pump is shut down.
A centrifugal pump should be used to feed the hydrocyclones. A centrifugal pump will deliver a smooth even flow to the feed manifold. A reciprocating pump should not be used due to delivery fluctuations.
Proper solids control system installation should have the Desander’s centrifugal pump taking suction from the closest compartment possible downstream of the rigs' primary shakers. The Desander’s overflow mud should discharge into the next down stream compartment where the Desilter’s pump will take suction.
Hydrocyclone installation requirements are basically the same, and must be adhered to if optimum efficiencies are to be realized.
Centrifugal Pump Installation1. Each hydrocyclone manifold should have its own centrifugal pump dedicated to it’s
operation and sized correctly to satisfy the hydrocyclone’s pressure and volume requirements in order to achieve optimum operating performance.
2. The centrifugal pump should be located below the fluid level of the pit to allow for a flooded suction and to minimize pressure losses. A pump that must be mounted above the fluid level should include a foot valve.
3. The suction line to the centrifugal pump should be equal to or larger than the diameter of the pump’s inlet. If the suction line is longer than 10 feet, then the suction line must have a 2-inch larger diameter than the pump’s inlet to prevent loss of pressure head. The larger suction line should be connected to the pump suction with an eccentric reducer so that the top of the larger line is level with the top of the pump intake.
4. To minimize the risk of plugging the pump’s suction or causing damage to the pump with trash, the suction intake inside of the compartment should have an elbow facing down about 4 to 8 inches above the compartment bottom. If the suction is too high, a vortex will occur and draw air into the pump, resulting in poor hydrocyclone performance.
Pump Discharge/Hydrocyclone FeedProperly size the feed and suction lines. Oversized pipes will result in solids settling and undersized pipes will result in restricted flow and decreased pipe life. The feed line from the pump to the 4" hydrocyclone manifolds should be at least 6 inches in diameter, and 8 inches in diameter to a 12" or 10” hydrocyclone. Utilize long radius elbows to minimize pressure losses and wear in the lines.

Document number M9319Revision 8Page 12 of 48
3: Installation
OverflowThe overflow line (clean mud) should be directed to the next downstream compartment from the units suction. The overflow should not slope upward. This will prevent a possible back pressure in the hydrocyclone resulting in whole mud losses out the apex.
The overflow line should not extend below the highest expected mud level. A splash plate or opened tee installed at the overflow’s exit (discharge) will minimize aeration of the mud that would adversely affect the pump pressure. If possible, the overflow line should slope downhill at 45° to allow partial pipe flows that will prevent a siphoning effect.
ValvesOne valve in the pump suction line for pump repair and one in the discharge line to permit surge free startup operation will be adequate. Locate the pump so that the shortest suction line and the most direct discharge line route is accomplished, using as few bends and fittings as possible to reduce the frictional line losses.
Pump SuctionTo minimize operational problems, use these guidelines when designing or installing the suction line piping system.
1. One suction pipe for each pump.
2. Have a flooded suction. Oilfield centrifugal pumps are not self-priming.
3. Size the pipe diameter to produce 4 feet per second velocity or more.
4. Locate the pump as near the tank as possible. The shortest suction pipe produces the least friction losses.
5. Use straight pipe for smooth flow into the pump.
6. Properly sized the fittings for low friction loss.
7. Install a shut off valve near the tank for working on the pump.
8. Weld a flat plate on the tank wall just above the suction pipe to prevent vortexing.
9. Install an easily cleaned strainer for all mud going to the suction.
10. Avoid whirlpools, air leaks, air traps, and suction lift.
11. Install the suction near the bottom of the tank using an elbow and flare.

Operation
PrinciplesThe three most often mentioned components of the hydrocyclone are: the FEED, the UNDERFLOW, and the OVERFLOW.
Fluid entering the hydrocyclone is the “feed”. The feed opening (inlet) is at the top end of the feed chamber and enters the hydrocyclone at a tangent or involute to the feed chamber wall.
The solid / liquid slurry that exits the bottom of the cone is the solids discharge, or "underflow".
The liquid discharge that exits the top of the hydrocyclone is the "overflow". The overflow carries the light fraction (cleaned liquid) of the separated mud to the overflow manifold, and returns it to the mud system.
www.nov.com/brandt
Document number M9319Revision 8Page 14 of 48
4: Operation
As the fluid enters the hydrocyclone, it is propelled into a high velocity spiral moving around the "vortex finder" which extends down from the overflow exit. Actually two spirals are created, one moving downward along the wall of the hydrocyclone while the other moves upward through the core of the hydrocyclone towards the overflow opening. The centrifugal forces and inertia effect cause the solids to settle outward toward the hydrocyclone wall in a downward spiraling motion.
The solids settle according to weight and size, and with the density range of the solids normally present in drilling fluids being rather small, the size usually dictates which particles will reach the wall first. The liquid and most of the fine solids from the inner spiral move upward and outward into the overflow manifold and back to the system. The central air core in this spiral creates a low-pressure region that results in the suction that can be felt by blocking the apex opening with your finger tip.
The hydrocyclones' ability to separate the solids efficiently is dependent on the following factors:
1. Fluid properties
2. Particle properties
3. Flow parameters
4. Hydrocyclone parameters
This hydrocyclone design is referred to as "BALANCED". The solids traveling downward to the apex area will become highly concentrated due to the decreasing available area. The solids will exit in a vigorous "spray" discharge ("UNDERFLOW") . As previously mentioned, there will be an air stream (suction) entering the apex. These combined features are the ideal mode of operation of the hydrocyclone.
The “balance" design is unique in that, as long as the solids present in the feed mud are within the hydrocyclones' size range, the hydrocyclone will discard the solids. When the solids are too small or low in concentration, the hydrocyclones' "underflow" will discharge a minimal amount of liquid mud.
The efficiency of the hydrocyclone is affected by the flow rate, entering fluid velocity and pressure drop across the hydrocyclone. The hydrocyclones' efficiency will increase as the particle density and/or diameter is increased. As the fluid density and/or viscosity increases, the efficiency is decreased.
To maintain underflow with a density weight of 1.5 ppg more than the feed slurry, a smaller apex opening may be needed. It is difficult to estimate accurately the underflow discharge rate. However, it can vary between 1% to 5% of the feed volume to the unit.
A hydrocyclone discharging in a spray (resembling a hollow cone or umbrella) will achieve maximum solids removal. If the hydrocyclone becomes overloaded with entering solids, the solids are detained in the apex area resulting in reduced separation and rate of removal. The solids that would normally exit the apex are now returned to the system via the vortex finder or overflow. The solids that do report to the underflow will now be discharging in what is referred to as a "Rope Discharge".
The "Rope Discharge" underflow may contain as much as 30% more solids than a "Spray Discharge" but the actual rate of discharge is so restricted that the hydrocyclones may only discard 50% of the solids that it would while operating in a "Spray Discharge"

4: Operation
Rope versus Spray Discharge1. A rope discharge will not remove solids as well, even though the density is heavier. It looks
more efficient, but is not.
2. The system’s mud weight will increase faster due to the solids reporting to the overflow (density increase). Also, in unweighted systems the well bores filter cake will contain unwanted solids.
3. Only with additional mechanical equipment and/or through expensive dilution can the solids returning to the system be removed when roping occurs.
4. Premature wear at the apex, vortex finder, upper hydrocyclone body and rig pump fluid end parts will result, if a roping discharge is not rectified quickly.
This example above indicates that the hydrocyclone leaves 29,952 lbs or 33 BBLS of solids in the system daily when it ropes verses spraying. A mud system weight of 9.2 ppg with 6.5% solid content, would require 475 BBLS of dilution water for these solids to maintain the system's desired mud weight.
(33 BBLS/.065 = 508 BBLS - 33 BBLS = 475 BBLS water)
Centrifugal PumpCentrifugal pumps produce pressure by accelerating fluid to the impeller tip speed. The casing converts this velocity into pressure. The pressure produced by the centrifugal pump acts as if it was coming from a water tower. The pressure in PSI varies with the weight of the fluid, the same as it would if the water tower is filled with different fluids. “Pressure head” of the fluid remains constant at any density. A pressure head of 75 feet is required for maximum hydrocyclone efficiency.
Centrifugal pumps produce pressure by converting liquid velocity to static pressure. The system back pressure must equal the pumps produced head. The system pressure loss is the total of the elevation difference plus friction loss. The volume pumped by a centrifugal pump increases until the sum of elevation and system friction head loss equals the output head of the centrifugal pump on the impeller performance curve. Using a larger pipe will lower friction, allowing the pump to increase in volume.
When operating the centrifugal pump, the head will remain unchanged; pressure readings, on the other hand, will change if the weight of the fluid being pumped changes.

4: Operation
OperationWhen drilling the hydrocyclones should operate with a spray discharge for maximum efficiency. A slight suction at the apex discharge opening is proof of spray discharge. If suction does not exist, the hydrocyclones are "roping" and the apex needs to be opened up. If the hydrocyclone continues to rope with the apex wide open, consult the Troubleshooting Section for the cause and solution.
If flow rates indicate that blanking of hydrocyclones is necessary, blank off individual cones starting from the feed end of the header.
Start-Up ProcedureCheck pump suction, if visible. Clear trash and debris.
1. Open pump suction valve. Do not start pump with suction valve closed or pump damage will result.
2. Discharge valve should be closed. If diesel pump is used, check that throttle is in idle position. Damage and injury may occur if diesel pump is started at full throttle.
3. Start pump and slowly open discharge valve to full open position.
4. Check pressure on Feed Gauge. The gauge needle should be in the area corresponding to the mud weight. If the original feed gauge supplied with the unit is replaced with an ordinary pressure gauge, proper pressure is four times (4 X) mud weight (in ppg). Low pressure will cause poor separation and high fluid loss. Excessively high pressure will cause high rates of hydrocyclone wear. When testing with water the feed pressure is 32 PSI.
5. Check the hydrocyclone underflow for a spray discharge. If hydrocyclones have a rope discharge or no discharge, consult the Troubleshooting Section.
Example:
PSI = Mud Weight x 0.052 x Head (in feet)
Head = 75 feet
If: Mud Weight = 9.5 ppg
PSI = 9.5 x 0.052 x 75 = 37 psi
If: Mud Weight = 12 ppg
PSI = 12 x 0.052 x 75 = 47 psi
Do not operate hydrocyclones with a rope discharge because poor solids removal and hydrocyclone damage will occur.

4: Operation
Shutdown Procedure1. Turn pump off. If diesel pump is used, close throttle before shutoff. Do not use the
emergency kill switch (if supplied) for normal shutdown.
2. Close pump discharge valve.
3. Close pump suction valve.
Hydrocyclone Blanking1. Stop unit. Remove the clamp from the feed inlet of the hydrocyclone.
2. Remove clamp from the overflow elbow at the header. Support the weight of the hydrocyclone or damage and injury may result.
3. Remove the hydrocyclone and overflow elbow.
4. Install blanks and clamps. Start unit.
Apex AdjustmentHydrocyclones operated improperly will cause poor separation and should be adjusted or replaced as soon as problem occurs. Only the 12” hydrocyclone allows for apex adjustment. The 10” and 4” hydrocyclone are shipped from the factory with the optimum apex.
12” Desander Apex AdjustmentThe non-adjusting apex bushing is located in the adjusting nut at the bottom of the desander hydrocyclone. A bushing with 1-3/4” internal diameter is installed at the factory. 1-1/2” and 2-1/8” apexes are also available. If a change is required:
1. Remove the hydrocyclone apex nut by turning clockwise.
2. Remove the apex bushing from the apex nut.
3. Install proper size apex bushing.
4. Install the hydrocyclone apex nut.
10” Desander and 4” Desilter Apex AdjustmentThe apex adjusting bushing is located in the adjustable nut at the bottom of the desliter hydrocyclone. Proper discharge is achieved by twisting the adjustable nut as indicated below.
1. Start feed pump and check for spray discharge.
2. If excessive liquid loss occurs, tighten the adjusting nut to close bushing. Apex size will be smaller.
3. If roping occurs, turn clockwise to open bushing. Apex size will be larger.
Do not cross-thread. Hand tighten only.
Over adjusting may cause roping and dry plugging of hydrocyclones. Do not use a wrench on the adjusting nut. Hand tighten only.
If roping is not eliminated, remove the nut and bushing.

Troubleshooting
TroubleshootingFor such a basic appearing device, the hydrocyclone can display many varied problems. The following six (6) are the most frequently experienced in the operation of the hydrocyclones.
Symptom Probably cause Solution
Low feed pressure. Improper head pressure. Check with manufacturer for proper head pressure required and adjust pump as necessary. Pump impeller sizing must make up for variable pressure losses in the piping.
Plugged pump suction. Clean screen. Check for obstruction in pump and line. Make sure valves on suction and discharge are open.
Other equipment operating. Check that pump is not operating other equipment simultaneously.
Air locked pump. Prime pump. If suction is flooded, stop and restart the pump.
No discharge. Plugged apex. Unplug the apex.
Apex too small. Change apex to larger bore (12” hydrocyclone only).
Solids below hydrocyclone’s cut point capabilities.
No problem, working fine.
Siphon on overflow. Install vacuum breaker at highest point on overflow. Remove pipe plug in top of header and install pipe 6" to 8" long.

Document number M9319Revision 8Page 20 of 48
5: Troubleshooting
Discharge roping. Undersized apex. Change apex to larger bore (12” hydrocyclone only).
Check pump specification, feet of head too low.
Refer to section titled "Centrifugal Pump" on page 15.
Mud viscosity very high. Run centrifuge.
Solids overloading. Check that upstream equipment is operating properly.
Discharge weight near that of feed weight.
Apex too large. Reduce size.
Low silt concentrations. Evaluate economics of equipment.
Discharge weight greater than normal.
Roping discharge due to solids overloading.
Increase apex opening.
Check that upstream equipment is operating properly.
Unusual discharges. Cone shape or liquid discharge.
Feed inlet partially plugged causing a reduced feed velocity.
No discharge. Remove and clear obstacle.
No vacuum or flooded liquid rope discharge.
Feed completely plugged; can cause good overflow mud to enter hydrocyclone from the overflow manifold resulting in whole mud losses.
Plugged apex. Typical when roping is allowed to continue. Solids build-up in the hydrocyclone and overloads at the apex. Entering solids will report to the overflow and back to the mud system. Plugged apex will cause premature wear on the hydrocyclone and excessive wash out on overflow fittings.

Maintenance & Repair
MaintenanceDaily
1. Inspect and maintain feed pump in accordance with manufacturer's specifications.
2. Inspect hydrocyclones for spray discharge and proper pressure.
3. Repair or replace hydrocyclones that show signs of cuts, leaks or other damage.
Every 30 Days1. Inspect hydrocyclone apex for wear. Remove and visually inspect the apex. Using a
flashlight or mirror, inspect the interior of the hydrocyclone body. Replace worn parts as needed.
2. Remove clean out cap and clear feed header of settled solids.
3. Check all connections for tightness.
Desander Hydrocyclone Removal and Disassembly
1. Stop pump. Remove clamp from feed inlet.
2. Remove clamp from overflow elbow at header. Remove hydrocyclone from header. Support weight of hydrocyclone when loosening clamp or damage and injury may result.
3. Remove clamp and overflow elbow. Remove nuts and bolts from top flange. Remove top flange.
4. Remove nuts and bolts from apex clamp. Remove clamp halves and apex.
5. Replacement is the reverse of steps 1 - 4.
Note
Worn out apex can be changed by following step 4 only.
Note
A film of grease or oil will ease assembly of new top flange.
